IMPROVEMENT IN TWO-WHEELED VEHICLES.

Specification forming part of Letters Patent No. 195,663, datedSeptember 25, 1877; application filed September 1, 1877.

To all whom it may concern Be it known that I, EBON B. SIMPSON, ofBridgewater, in the county of Rockingham and State of Virginia, haveinvented a new and valuable Improvement in Sulkies and other Two-WheeledVehicles; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a vertical section, showing the manner ofhinging the shafts to a two-wheeled vehicle. Fig. 2 is a bottom view ofa sulky to which my improvement is applied.

The object of this invention is to relieve sulkies, carts, and othertwo-wheeled vehicles of their characteristic unpleasant vibratory motionin traveling; and it consists mainly in the substitution, for therigidly-attached thills heretofore used, of thills which are hinged, sothat the up-and-down motion of the horse is not communicated to thevehiclebody.

The several details of construction and subsidiary features of myinvention will be hereinafter fully described, and their operationexplainod.

In the drawings, A designates the body of I a sulky, and B the shafts orthills thereof. To the under sides of the inner ends of these shafts aresecured the wings O of hinges, the other wings, O, of which are attachedto the under sides of thebottom side timbers of the body A. To theforward wingsOof said hinges are secured bent arms F, which extendrearward under the wings O. The function of these arms F is to preventthe body A from turning backward on the axle, owing to the flexibilityof the hinges, as it will be seen that, if the body turns upward unduly,the said arms will strike against the hinge-wings 0.

At the rear end of each shaft a socket, E, is formed, within which isarranged a rubber block or spring, 6, and on the forward ends of thebottom side bars or timbers D of the body A are formed tenons d, whichfit into the sockets E and against springs e. By this ar rangement thebody is relieved from jolting at the termination of the downward motionsof the thills, which result from the natural movements of the horse.

The essential principle of my invention may be applied to a two-wheeledvehicle, provided with a tongue and employing two horses. This may beaccomplished by hinging to the front of such vehicle a bow, the ends ofwhich take the places of the ends of the shafts in the drawings, andattaching the tongues to the middle of said how.

Having now fully described the construction, and explained the operationof my invention, I claim-- 1. A two-wheeled vehicle, having shafts or atongue hinged to its body, and provided with springs at the hinges, andarms F, to prevent overtilting backward.

2. The combination of hinged shafts B, body A, springs c, and arms F,substantially as described.

3. The combination of hingedshafts B, arms F, and body A, substantiallyas set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

EBON BUSHBOD SIMPSON.
